Remove and Replace Chassis Cover
Cisco 4000 Series ISRs have a removable cover. The tasks that you perform for removing and replacing
the router cover are based on the specific model of the Cisco 4000 Series ISRs.
See the relevant removing and replacing sub-section for your specific router in the Cisco 4000 Series
ISRs:
• Remove Cover from Cisco 4400 or 4200 ISR
• Remove Cover from Cisco 4300 ISR
• Replace Cover on Cisco 4400 or 4200 ISR
• Replace Cover on Cisco 4300 ISR
Caution Do not run the router with the cover off. This can cause the router to overheat quickly.

telephone-network voltages. Statement 1041
